I can provide database design and implementation as well as database optimization and overhaul. The bulk of my experience is with MySQL and PostgreSQL but other options can be discussed. Custom schema can be created from specifications given by the customer and implemented using their database. If the database needs to be set up, I can install the database and the custom schema but hosting costs and or ongoing administration will need to be negotiated separately or handled by the customer. If you have databases in need of optimization or overhaul I can do that too. Tasks like migrating data to a new format or adding indexes are within my scope and other options can be discussed if you needs are more specific.
